Fretting amplitude map of martensitic stainless steels [PDF]

open access: yes, 2019
On the basis of well-known dependence fretting process from the sliding amplitude [1], experiments was performed in order to verify the dependence of fretting process upon the slip amplitude. The reason is that the dependence of the fretting process from

Micro-mechanical modelling of fretting fatigue crack initiation and wear in Ti–6Al–4V [PDF]

open access: yes, 2014
A micro-mechanical modelling methodology is presented for predicting fretting fatigue crack nucleation in Ti–6Al–4V. The methodology is based on a combination of (i) a unit cell crystal plasticity model of Ti– 6Al–4V, (ii) a frictional contact model of ...

Fretting fatigue life prediction using the extended finite element method [PDF]

open access: yes, 2010
In this work, fretting fatigue tests available in the literature are modeled using the extended finite element method (XFEM). The aim is to numerically evaluate the stress intensity factors (SIFs) for cracks of different lengths emanating at the end of ...

Improvement of the fretting fatigue and fretting wear of Ti6Al4V by duplex surface modification [PDF]

open access: yes, 1999
Ion-beam-enhanced deposition (IBED) was investigated as a way to increase the fretting fatigue resistance of Ti6Al4V. Both hard CrN coatings with good toughness and soft CuNiIn coatings of low friction have been applied on the base material, and shot ...

A Development and Application of the Fretting Fatigue Test Apparatus

open access: yesMATEC Web of Conferences, 2016
Fretting fatigue occurs in contacting parts which are subjected to fluctuating loads and very small sliding movements at the same time. Fretting fatigue can significantly reduce the fatigue life of materials.
